    <issue

        id="LintError"

        severity="Error"

        message="No `.class` files were found in project ".", so none of the classfile based checks could be run. Does the project need to be built first?"

        category="Lint"

        priority="10"

        summary="Lint Failure"

        explanation="This issue type represents a problem running lint itself. Examples include failure to find bytecode for source files (which means certain detectors could not be run), parsing errors in lint configuration files, etc.
These errors are not errors in your own code, but they are shown to make it clear that some checks were not completed.">
